Profile: Health Science Products, LLC manufactures quantitative fluid analyzers. Our quantitative fluid analyzer (QFA™ 300 & QFA™ 3500) is an instrument that measures pH, oxidation reduction potential (REDOX) adjusted for pH or rH2, resistivity & temperature of bodily fluids such as saliva, urine and water. The in vitro analysis provides the practitioner with general information regarding digestion, free radical load and mineralization to assist the practitioner recommend diet and lifestyle recommendations. The analyzer includes sensors that measure the fluid parameters by converting the reaction at the cell to a weak electrical signal. The signal is wired to the analog to a digital converter module (ACDM) via the sensor cable harness. The amplified signal is routed to a personal computer (PC) over the RS-232 cable. The PC stores the digital information and processes it with special QFA software. The Iodide QFA™ 1500 is an instrument that precisely measures iodide concentrations in body fluids including saliva, whole blood and urine. It is a self contained instrument with a touch screen display that simplifies all operations. The analyzer uses a specific ion electrode (ISE) in a small 2 cc sample cell.
